EDGE: "Power struggle: the real differences between PS4 and Xbox One performance"

Read it again, It was a comparison of investment of servers for their consoles a little reading comprehension goes a long way, If you think MS built Azure for XB1 your crazy.
You still don't have numbers to prove this. Isn't this just tales from my ass stuff?
 
I am trying to understand the new revelations on how ESRAM bandwidth has been calculated, and the explanation for what they were able to measure.

Please correct me if I am wrong.

1. What was described as an accidental discovery of simultaneous read/write capability in the ESRAM was perhaps just new to the developer who leaked the Microsoft blog. The engineers are not THAT incompetent.

2. It seems the ESRAM has 4 main modules, each with a 256-bit interface (27GB/s). They call it 1024bits (109GB/s) as the 4 modules can be accessed in parallel. The catch is that the data must be simultaneously present in all 4 regions in order to achieve 109GB/s (or 218GB/s simultaneous read/write). Hence, "of course if you're hitting the same area over and over and over again, you don't get to spread out your bandwidth and so that's one of the reasons why in real testing you get 140-150GB/s rather than the peak 204GB/s". In a theoretical moment where the data was in only one of the 8mb modules, the bandwidth would be as low as 27GB/s (54GB/s simultaneous read/write).

In contrast, the whole PS4 GDDR5 memory is interfaced at 256 bits at 5.5ghz. The rate (256 ÷ 8 x 5500 = 176000MB/s) is not dependent on access patterns. Hence, I presume, the practical bandwidth being closer to the theoretical maximum.

3. From Wiki (I know) it appears SRAM with separate I/O buses (as opposed to a common I/O bus) exists that can read and write at the rising and falling edges of a clock signal respectively, using a single port. The catch is that the read and write operations are pipelined and sequential (a read must be followed by a write in the pipeline) to the same memory space. This explains why "if you're only doing a read you're capped at 109GB/s, if you're only doing a write you're capped at 109GB/s". I presume this suits blending operations well, which Leadbetter alluded to in his earlier article. It also suggests that Microsoft fully expects developers to use the ESRAM for framebuffer operations.

Further suggestions welcomed.



The PS4 memory is also arranged in separate modules that add up to a 256-bit bus. IIRC the PS4's memory is arranged in a 16 memory module setup each module is 16-bit, the sum of which is 256-bit. The memory controller is still 256-bit and the pool is seen as one. It works this way for GPUs as well, it's not just one slab of 8GB @ 256-bit or a group of modules each @ 256-bit.

What are exactly the advantages of dedicated servers over P2P?

Will there be a problem of servers for certain games being shut down in the future and not working online anymore??

Nothing! I said nothing!
sony have said nothing, But Rackspace have.

Said they have a deal with Sony. That is it, everything else is assumption. It could be for Gakai, it could be to get downloads speeds upto Xbox levels, it could be for cloud dedicated servers or anything else.

You are just assuming that Sony has something and they might well have nothing, like I said secret sauce.

God forbid that the Xbox One should be stronger than the PS4 in any way shape or form.
 
I was thinking maybe all of it?

As far as the power struggle goes this is becoming Sonys secret sauce. Sony has the more powerful machine and just about everyone accepts that.

MS is stronger online, they always have been and they have detailed what they are doing to continue to be next gen. Why can't people accept this? Not that it will necessarily always be the case but Sony have said nothing and people are assuming on their behalf.

No one's denying MS has the better online infrastructure, but Skeff's point was that MS was leveraging off the Azure segment of the MS business. Azure is not some dedicated Xbox-only server.

In terms of infrastructure investments for pure-gaming made by SCE, Sony's made strides with SOE's expansion, Gaikai purchase and their new partnership, which was made by SCE and not Sony.

Will these stuff make PSN better than XBL? Who knows, and I don't think so, personally. But SCE's investments have been significant from a pure gaming infrastructure standpoint.

Do note that SCE's Gaikai investment is basically what MS is planning to do in 2015/2016 based on their Fortaleza roadmap anyway.

Jesus fucking christ.

The mental gymnastics some of you make to justify the XB1's weaker hardware is just...wow.
Well... I mean... You have to understand that the XB1 is a well balanced machine. And while you think HW specs matter, in reality, hardware specs are meaningless - even if its just a slight bump in CPU power. Because its not about balance or specs or 3rd party devs siding with PS4, its about the Cloud. Where else can you find 600% more AI? Surely not on PS4. I mean... We have games taking advantage of the cloud requirement to improve AI freeing up 10 or 20% more power for graphics... But the magical part is that the game doesn't require you to be online!

That's just how good dat MS kool-aid is. You have to stop ignoring it.

BTW the xb1 will be stronger than the PS4 in some ways, but we cannot say online just yet.

For multiplayer games it does not tent to matter, because by the time servers are closed practically no one is playing the game. Dedicated servers requirement in single player only game is big no no. In those cases it tends to mean some sort of DRM.

You've got to understand there are certain posters on here who genuinely think there is nothing the Xbox One is going to be better at than the PS4. There are posters right now that think PSN is already on the level of Xbox Live in terms of service and options. I wouldn't read too much into it.

I know this is not true for many parts of the world, but XBL's consistency of service is piss-poor compared to PSN here.

Mind you, this is MS's fault more so than Sony outperforming MS. I don't know what the hell they have going here that the service is so inconsistent.

Well we know of nothing MS have done specifically for the xbox one. apart from marketing, yet we know Sony have:

a) purchased Gaikai
b) are deploying an openstack private cloud.

AFAIK, from the known information we have, It seems i'm right, so unless you've got any info stating there are specific costs for Xbox live that cost more than deploying an entire cloud service or buying gaikai, I'm willing to use this as "proof enough"

For all I know Sony could have the greatest online infrastructure the world has ever seen ready to go on launch day. If they do i'll be delighted.

At this point though they have said nothing and they are not the type of company to say nothing. Until they say something I am going to assume their setup at launch will be similar to PSN just now only a bit faster with Gakai and other improvements to follow.

I never understood XBL having a better online infrastructure being taken as a fact

Where is the hard evidence?

Do we have the actual number of games on either system that have been proven to have dedicated systems? (PS3 & X360 I mean)

It always seemed to be an assumption to me

Although I'll certainly conceded that PSN download speeds seem to be worse but that didn't seem to be the discussion here

Sony have been playing catchup the whole generation. Slowly adding features but the user experience on PSN isn't as good and it certainly isn't as fast, for me that is because I can't speak for everyone else.

As far as dedicated servers go, as far as I know a few Sony games had them and no MS games.


EDIT to add info from ShapeGSX: A number of Xbox 360 games had dedicated servers. Gears of War 3 and Judgement and Left 4 Dead 2 are the ones I can think of off the top of my head.

I don't know if MS has the better online infrastructure. I am extremely familiar with OpenStack, Azure, and Rackspace, and I personally would take the Rackspace infrastructure every day of the week.

We don't know how SCE will utilise their Rackspace partnership, or at what stage are the integration of the infrastructure is at the moment.

We do know that Sony's taking it very seriously, though there hasn't been a lot of details for all of them.
 
There is a difference between scene complexity, draw distance, lighting, framerate, physics, ect. and resolution. The average consumer will be able to tell the difference between nextgen and current gen watchdogs. but they most likely wont be able to tell the difference between native 900p upscaled and native 1080p next gen watchdogs. However, that doesn't mean the difference isn't there.

Actually depending on the distance you won't notice the difference between Ps3 Battlefield and PC battlefield. You won't notice the difference from the Vita and the DS if you are watching far enough.

It's a bs argument, and there's no reason to sit almost 10" away from a 40" T.V either. Also mishandling of technology means nothing, since many played Xbox 360 with composite too and I'm not going to stand here and act like that means anything for me.

So just as a guideline:

THX
Screen Size Recommended Range
35" 3.5' – 5.0' (1.0 – 1.5 m)
40" 4.0' – 6.0' (1.2 – 1.8 m)
50" 5' – 7.5' (1.5 – 2.2 m)
60" 6.0' – 9.0' (1.8 – 2.7 m)


And don't forget to plug in the HDMI cable too!

Seem to have ruffled some feathers in here so I'll try to make an equivalent promotion of XB1 over PS4.

It seems to me MS have invested more in creating original TV shows for their games console than Sony.

Does everyone see the similarities here, Microsoft are making a Halo TV series specifically for XBL, However Sony's shows are on TV, such as Breaking Bad.

That is the intent of which I meant the statement. Perhaps with both statements to look at, both sides of the console war will understand.

Anyway, I'm out for a while got some Breaking bad to catch up on.

As the shape mentioned there are several MS games with dedicated servers

A number of Xbox 360 games had dedicated servers. Gears of War 3 and Judgement and Left 4 Dead 2 are the ones I can think of off the top of my head.

My point was about online infrastructure (servers) not online features (voice chat etc.)

So yes the overall online experience has certainly been more feature-rich on XBL on X360 but the dedicated server argument is a toss-up for now in my mind

Both systems this gen have had dedicated servers for a handful of games

I don't see any reason to believe that's going to greatly change next gen

Some games will have them some won't for both consoles

The fact that MS is offering them at some sort of discount is nice but doesn't prove to me their online infrastructure is going to be better overall

Online features we could argue about for next gen until we're blue in the face but at least Sony should have those features missing from PS3's online experience

The whole TV situation for Xbox vs Sony is strangely ironic and hilarious.

If there was one company that literally has the perfect infrastructure and resources to do what MS is doing, it's Sony, with their entertainment division that has been responsible for many high quality shows. And they're already in the process of making such content, like the Watch_Dogs and Gran Turismo movie.

And yet Sony will never do what MS does, and make them exclusive to Xbox Live, because Sony's entertainment division is about getting their products everywhere, and they would most likely almost never restrict their content to only one distribution channel.

thats how corporate world works. COD is Acti game and Sony can say jackshit without actis permission... We do not know what deals acti has with MS if none (regarding this, mentioning ps4 or its servers). Your post came off as really ignorant.
ok then, why are we then supposed to assume that the ps4 version will have dedicated servers?

Microsoft has promoted dedicated servers at every opportunity, they have set up systems so third parties can get access to them at a significant discount, and all of their first party games that could benefit from them are using them.

Sony hasn't done this. They spend their tim talking about the power of the system. and the only time they even talk about servers is when they are talking about backwards compatibility.

so why is it so outlandish to assume that more x1 games will have dedicated servers? Both microsoft and sony are boasting about the advantages they have over their competition. Sony had power, cost, and ease of use. Microsoft has "the cloud" which is dedicated servers. Not that Son wont have them mind you. But more x1 games will use them.
 
ok then, why are we then supposed to assume that the ps4 version will have dedicated servers?

Because MS's favourite word, exclusive is missing from any conversations whatsoever regarding dedicated servers for CoD : Ghost.

When MS was asked to comment, they didn't say it was exclusive. When IW was asked to comment, they asked us to wait for more news on other platforms.

MS uses the word exclusive from everything from DLC all the way to Titanfall's 'next-gen console exclusive', and for this one thing, they don't use it?

Well if you look back at the pre PS3 launch spec analysis on NeoGAF.. It was all over. Cell was here to obliterate the 360. Game over. MS AM CRY! Your done son....

...only reality didn't really turn out that way.

PS4 isn't like the PS3, though. It's much more easier to develop games for now.

The only reason why PS3 had mostly bad multiplats is because of the cell processor in which it was very difficult for 3rd party developers to make games for the console. That's it.

Even once the consoles are released were not going to have any closure on this. If I am understanding things correctly, the Devs for PS4 only knew about the 4 extra gigs of RAM since February. So they have had very little time to really make use of that extra power. The Xbox One isn't really maximizing their potential either due to not being able to fully utilize "The Cloud", and their more complex construction. We're going to be at least the next holidays releases before we are going to see a difference. Not even necessarily then TBH. If the XB1 successfully recovers from their early PR blunders, and somehow manages to maintain parody with Sony in console sales. Titanfall explodes into some kind of mega game like HALO. We're looking at Devs having little choice but to ignore the specs and just port games to PS4, like they did this past generation. I have heard this in other threads. XB1 isn't going to be ignored no matter what the specs are. MS has too much influence with the big players. So a weaker XB1 could be the worst possible news for PS4 owners. Especially early adopters.

While the Xbox brand is popular in America, the Playstation brand is still more hugely popular than the Xbox brand is everywhere else, even in America with people like myself.

So no, they don't exactly have a lot of influence with the big players. Microsoft's not the Don Corleone of the gaming industry.

I am assuming just about every MS game is going to have them. The big hitters at launch do and Halo and Titanfall will. The main benefit of the cloud is that it makes it cost effective to have dedicated servers, as far as I understand dedicated servers also allow for better graphics as well.

No. You can have some CPU stuff done server-side (A.I. in multiplayer games for example), but offloading graphical workloads ain't happening anytime soon.

Not to say it wont ever happen; I'm aware of that nVidia tech demo thingy from a few months back, but that kinda stuff is way early in development, not to mention the infrastructure necessary to support it to the level that would be necessary for MS to use for a console-wide audience would require a massive additional investment on their part

I thought that because no player had to be the host, it gave you like 10-15% or something extra to play with.

What bottlenecks does the PS4 have that the XB1 does not?

I have yet to hear any clear advantage the XB1 has architecture-wise over the PS4

The peaks of memory bandwidth perhaps?

Has there been any breakdown given as to what percentage of the time XB1's memory bandwidth will be usable at any specific bandwidth?

I know PS4's is supposedly at least 140GB/s at any given time

Other than that I fail to grasp any other real advantages the XB1's architecture truly has

And that's that's perfectly fine to assume

I don't really believe there has been enough evidence to suggest as much considering MS's history with the X360 but I don't know for sure

What XB1 games have been confirmed to have dedicated servers again?

Is there a thread on it yet?

I know COD will, Titanfall will

Maybe Forza and Ryse?

Oh and the better graphics doesn't really work that way as you'd end up using more CPU. maybe a bit more ram not the graphics card resources for it

So more likely to have somewhat better physics or faster AI computations I would think

Still trying to track down one of those 'technical fellows' i would imagine.

I think Forza and Ryse do, not sure, Battlefield, COD, Halo and Titanfall do though. For the improved graphics I was only meaning because nothing has to be reserved as one person has to be host rather than anything to do with offloading to the cloud or that.

It is speculation, but is it so hard to believe? Microsoft already have a huge part of the infrastructure in place. They have been building Azure infrastructure for years. It's actually becoming one of of their main sources of revenue from corporate clients.
To segment a portion of those resources and assign it exclusively to Xbox isn't a huge investment, specially if they have an efficient process of scaling availability.

Depends on the opportunity costs associated with Azure usage.
 
I think Forza and Ryse do, not sure, Battlefield, COD, Halo and Titanfall do though.

Right so 2 of the big 3rd party games have dedicated servers which makes a great talking point but will AC4, watch dogs, destiny, minecraft, fifa, madden, need for speed rivals, the crew etc.

The fact that MS has made it a talking point about COD and BF having dedicated servers suggest to me that its likely not going to be as common as you might think

It's still a cost to 3rd party devs, regardless of how "significant" a discount there is

For the improved graphics I was only meaning because nothing has to be reserved as one person has to be host rather than anything to do with offloading to the cloud or that.

Right but that wouldn't free graphics resources as it wouldn't be handled by the graphics card so while there is likely something that can be improved graphically from the small amount of CPU, ram resources that are freed by dedicated servers (not sure how much that would really be to be honest) it is not going to be 10-15% extra power
 
I'm still thinking there will be a lot of parity between multiplat games. The Ps4 version will not blow the xbone version out of the water on many, if any, multiplat games. If I'm wrong I'll eat my hat.

The Respawn guy said it allowed for better visuals and sound. That's where I got it from, but he never put a number on it.
